Every one of our snowmobile rentals in Revelstoke is a current-year machine, so the choice comes down to power and track. Turbo machines (Polaris BOOST, Ski-Doo Turbo R) pull hardest at elevation and suit experienced riders. Naturally aspirated 9R and 850 E-TEC sleds are lighter on the wallet and plenty for most days. Go 165″ for deep snow and climbing, 154/155″ for trees and tight terrain.
